REFLECTOR FOR WATER-GAG ES.

SPECIFICATION forming part of Letters Patent No. 485,451, dat d,November 1, 1892.

Application filed March 22, 1892. Serial No. 426,019. (No model.)

To all whom it may concern:

Be it known that I, EZRA O. CARLETON, a citizen of the United States,residing at Port Huron, in the county of St. Clair and State ofMichigan, have invented new and useful Improvements in Reflector-Shieldsfor Water- Tubes; and I do hereby declarethe following to be a full,clear, and exact description of said invention, reference being had tothe accompanying drawings, and to the letters of reference markedthereon, which form a part of this specification.

This invention relates to a shield or reflector for water-tube gages, inwhich the height of the water in the boiler or other receptacle isindicated by the water-level as shown by the water-tube, and is designedespecially as an advertising medium, while at the same time performingits mechanical function.

The object of my invention is to provide a reflector or shield forawater-tube which can be readily attached to the tube and gotten up at atrifling expense and having instead of the usual numerical scale thename of a firm or other matter, the letters of which are arranged in acolumn and at equal distances apart to occupy exactly the position whichthe numerals would have, it being the purpose to distribute gratis thereflector to those having to do with boilers and other devices requiringindicating-tubes, so that while the reflector is performing its ordinaryfunction the name or other matter expressed by the arrangement of theletters will be thoroughly advertised.

The invention therefore consists, primarily, in the novel application ofletters on a reflector for water-tubes, arranged in the form of acolumn, so as to expressa name, sentence, or other matter when read fromtop to bottom, or vice versa; and the invention further consists in theconstruction of reflector with the spring retaining-arms by which it canbe readily applied to the tube.

In the accompanying drawings, in which my invention is fullyillustrated, Figure 1 is a view in front elevation of thereflectorshield, and Fig. 2 is a front view of the re flector applied toa water-tube. v

Referring to the drawings, the shield A is preferably made of thin sheetmetal and in half-round form. This may be enameled white or any suitablecolor to form a background on which the name or other matteris arrangedin high contrast therewith, so as to be readily seen through the water.The letters which are below the water-level are, by the magnifyingqualities of the cylindrical body of water inclosed in the tube,enlarged so that the level or height of the Water, which is oftendifficult to determine, is known to be between the small and themagnified letter,

or up to the highest enlarged letter, which is 7 made readily visibleunder nearly all circumstances. The curved sheet of metal is provided atboth top and bottom with spring retaining-wires B, which are made intosemicircular form, but having the ends flared out so that they can bereadily sprung on the tube and hold the shield in its. place. behind thewater-tube 0. These spring-wires are held in place by bending the endsof the reflector about them, as shown at D. In the drawings the water Dis represented as reaching the letter O, the water-line being seenataglance to be at this point from the enlarged size of the topmostletter reached by the water.

Having thus described my invention, what Iclaim, and desire to secure byLetters Patent, is-

Asa new article of manufacture, a shield or reflector consisting of acurved strip of sheet metal and the curved wire-frames at its top andbottom, around which is bent the upper and lower edge of said strip,said wires projecting out and flared to form the spring retaining-armsfor holding the shield in place, substantially as set forth.

In testimony whereof I affix my signature in presence of two subscribingwitnesses.
